Brocchi's Cluster (or The Coathanger)

Ce curieux astérisme (ce n'est pas un amas ouvert, comme on l'a longtemps pensé) se trouve dans la constellation du Petit Renard (Vulpecula),
mais il est parfois décrit comme étant dans La Flèche (Sagitta).
Il se compose de six étoiles alignées, accompagnées de trois étoiles en forme de crochet.
Cet astérisme mesure 90 minutes, soit trois diamètres lunaires. Il est visible à l'oeil nu, et admirable aux jumelles.
Le premier à l'avoir décrit est l'astronome perse Abd ar-Rahman al-Soufi (903 - 986 apr. J.-C.),
dans son livre "Le livre des étoiles fixes", publié en 964. Grand traducteur arabe de l'astronomie
grecque, il découvrit aussi le Grand Nuage de Magellan et probablement M 31, la Galaxie
d'Andromède.
Autres dénominations: la Nébuleuse d'Al Sufi, l'Amas de Brocchi, L'Escargot

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
